VERFAHREN UND VORRICHTUNG ZUR REGELUNG EINER PERMANENT-MAGNETERREGTEN SNCHRONMASCHINE MIT REDUZIERTEN LEISTUNGSPENDELUNGEN IM OBEREN DREHZAHLBEREICH |
摘要 |
The invention concerns a method and an apparatus for field-oriented control of a permanent-magnet-excited synchronous machine. Conversion of an ascertained longitudinal voltage component and an ascertained transverse voltage component into triggering pulses for the synchronous machine is accomplished in a low rotation speed range using a pulse-width-modulated inverter, and in a high rotation speed range using a block switching mechanism or a software program functionally corresponding to a block switching mechanism. The invention reduces output oscillations in the upper rotation speed range that occur in known systems as a result of angular inaccuracies with respect to the target voltage zero transition and the voltage zero transition that is actually implemented. |
